BlueSolar PWM-Pro and PMW-Light
Victron PWM (Pulse Width Modulator) solar charge controllers function as the switch between the solar array and battery. When the voltage provided by the solar array falls outside the ideal conditions for charging the battery, the PWM solar charger will shut off that flow, preventing the battery from overcharging and damaging the battery.

The BlueSolar PWM-Pro series of solar charge controller include:
- Lighting control function, fully programmable.
- Three-stage battery charging (bulk, absorption, float), fully programmable.
- Integrated battery monitor function (Remote Panel needed to display state of charge).
- Load output with low voltage disconnect and manual control (default setting).
- Optional external temperature sensor.
- Load output protected against overload and short circuit.
- Protected against reverse polarity connection of the solar panels and/or battery.
- Day/night timing options: see manual Remote Panel for details.
BlueSolar PWM-Light series of solar charge controllers includes:
- Load output with low battery voltage disconnect function.
- Lighting control function, one timer only.
- Two-digit seven-segment display for quick and easy setting of the load output functionality, including timer setting.
- Three-stage battery charging (bulk, absorption, float), not programmable.
- Load output protected against overload and short circuit.
- Protected against reverse polarity connection of the solar array and/or battery.
- Day/night timing options: see manual for details
